Answer:
10 units
Step-by-step explanation:
Given that:
Cos a = 3 /5
From trigonometry ;
Cos θ = Adjacent / hypotenus
Side Adjacent angle a = 3 = FD
Hypotenus = 5 = DE
3 / 5 = FD / DE
FD = 6 units
3/5 = 6/DE
DE * 3/5 = 6
DE = 6 ÷ 3/5
DE = 6 * 5 /3
DE = 30 /3
DE = 10 units
Answer:
The number of candles will hold 2 candles
And large candle holder will hold 6 candles.
Step-by-step explanation:
Let the number of candles small candle holder have x
And the number of candles large candle holder have y
So, according to the information given in the question:
17 small candle holders means 17 x
and 2 large candle holders means 2y
using a total of 46 candles means (1)
Similarly, 8 small candle holders and 2 large candle holders, for a total of 28 candles gives:
(2)
We will solve equation (1) and (2) by elimination method:
Subtractijng the two equations we get:
Substitute x=2 in equation(2) we get:
So, the number of candles will hold 2 candles
And large candle holder will hold 6 candles.
